  • Two-lane facility with 12-ft. driving lanes
  • 1-ft. shoulder widths
  • Inadequate vertical alignment
  • Annual average daily traffic
  • Current (2017) =2,600 vehicles per day
  • Projected (2037) = 3,600 vehicles per day

  • Improve safety
  • 96 collisions recorded from 2006 through 2016
  • Collision rate for western half of the project is 1.5 times

the statewide rate for similar facilities

  • Provide a facility which meets current design standards
  • Correct sight distance due to substandard vertical alignment
  • Provide adequate shoulders and clear zone

Segment A: Comparison of Alternatives

slide-21
SLIDE 21

Alternative 1 – Improvements on Existing Alignment

  • Minimal improvements
  • Lower geometric standard (lower design speed)

Alternative 2 – North Offset

  • Good improvements
  • Lower offset alignment cost

Alternative 3 – South Offset

  • Good improvements
  • Most potential residential relocations
  • Highest cost

Segment A Preferred Alternative: Alt. 2, North Offset
